Three epiphyseal fractures (distal radius and ulna and proximal radius) and a diaphyseal ulnar fracture in a seven-year-old child's forearm.

The authors report a rare case of fracture separations at both ends of the radius combined with an epiphyseal and diaphyseal fracture of the ipsilateral ulna. A seven-year-old girl fell one story and sustained a closed injury of her forearm. A closed reduction was unsuccessful, and an open reduction was performed with three of the four fractures being secured with Kirschner wires. These wires were removed one month later, and range-of-motion exercises were started. Thirty months after surgery, both forearms were equal in length, although the proximal radial epiphyseal line appeared partially closed. Joint motions, including forearm rotation, were normal. Radiologically, the ulnar diaphysis and the radial neck were posteriorly convex 20 degrees and 18 degrees, respectively.
